To all whom-may concern: s

Be it known that I, CURTIS C. LILLI- BRIDGE, a citizen of the UnitedStates, residing at Hutchinson, in-the county. of Reno and State ofKansas, haveinvented certain new and useful Improvements in Oil-Burners;and I do declare the following tobe-a full, clear, and exact descriptionof the invention, such as will enable. others'skilled' in the art towhich it appertains to make and use the same. I a

My invention relates to that class of burn ers known as oil gas burners,in which hydrocarbon oils are first vaporized and then burned.

The object of the invention is to provide an improved burner oi thisclass which may be usedin stoves, ranges, furnaces or other fire boxes,as a substitute for other fuels.

A special object of the invention :is to improve such burners with a.view toreduc: ing the number of parts, and'consequently (the cost, andincreasing the efficiency or heating capacity.

Vith this and other: objects inview, -my invention consists intheimproved-construe? tion, arrangement and combinationof parts of a'burnerof this class, w hich will be more b the complete burner taken on adiametric plane; Fig. 4 represents a bottom plan view' of the uppermember or. spreader; and Fig.

5 represents a top plan view of the lower or base member.

Like reference characters mark the same parts wherever they occur in thevarious figures of .the drawing.

Referring specifically to'the drawings, 1

indicates the base member and 2 the upper member or spreader. The basemember 1 is preferably, in the form of a circular bowl having its,sidewalls inclined inwardly towiird its lower end and provided, at a shortdistance inwardly from the lower end, with displacement when in use.

a ring 3, concentrically located with reference to the walls of the bowland connected thereto by'an annnlarporti'oni of thebottorln, forming anannular drip ordrain channe 0.

The ring 3 is slightly conical, its

walls inclining inwardly from theirbottmn upward and mounted on andintegral with the upper edge of said'ring, .is a skeleton truncated cone6 which is interrupted by a plurality of segmental draft open ri =7alternating with radial arms 8, which are provided with grooves orchannels 9 in-their.

upper faces, merging into the'upp'er-part 10 of the cone, whichiscentrally provided with a segmental depression 11 from the center ofwhich depends an oil supplypipe 13.

'The upper member or spreader 2. comprises a structure ot substantially:inyerted truncated conical form, the central portion of the bottomthereof being provided with a segmental recess 13 which, when :thismemher is in position on the basemcmber, as

shown in Figs: '1' to 3 of. the. drawings, is

seated upon and partially incloscs the up-v per end of the interior coneof, the base member. The upper portion of the spreader,-

or upper member 2'is made hollow as at 14 in order to lighten thestructure. Projecting radially from the upper edge of the upper member2' are arms 15,.v'vhich are of a proper length and beveledlon'thfeirou'ter ends at 15 .to engage vpartiallyfin,the' upper end of thebase member 1, when the memher 2 is resting thereon. as before"describei' said arms entering partiallyinto the bowlof the base memberand serving to st eadyf the. upper member or spreader and-prevent its Inthe use ofmy inventibn,"oi l' supplied through the tube 12 rises intothe depression 11 at the summit of the interior cone of the base member,and when' a sutlicient amount has entered this depression, it overflowsinto and through the channels 9, finally reaching the annular drip ordrain channel 5. When the oil is lighted. it heats all parts of theburner and the oil'coming in contact with the heated parts rapidlyvaporizes and is consumed in its'vapor form, the inverted conic-a1 formof theupper member or spreader 2 serving to spread the blaze. andsufficient air is provided through the draft openings 7 to properly' mixwith the vaporized oil. and burn with an in tensely hot fiame.

By reason of the necuhar arrangement of parts, as described, the oilsupply pipe is not exposed to the flame and is, therefore, in no that Ihave reduced the number of parts of burners of this class to two only,and that these parts are of simple construction, pref senting no formsdifficult to manufacture.

I My bu rncr may, therefore, be ve v econom1- 'cally constructed and,inasniuci as thev parts are of stout, heavy construction, they will notbe-liable to be cracked by expansion or contract-ion due to heat orcold, nor'will they be liable to breaka' e in ordinary use.

\Vhil'e I have speci cally. described the exact construction andarrangement of V9.- rious parts of my burner, it will be obvious tothose skilled in the art that changes and variations may be made in theform of the parts without'departing from the spirit and scope of theinvention.

Having thus fully described my invention what I claim as new and desireto'secure by Letters-Patent is:

1. A burner of the class 'describedcomprising a base having a centraldraft opening and an annular drip channel, an integral ring rising fromthe base around said opening and forming the inner wall of saidchannel,'upwardly converging arms formed integrally with said ring withsegmental open-. ings between them, the upper sides-of the, arms havinggrooves leading to said channel, and a truncated cone formed integralwith the upper ends of said armsand having an oildepression.communicating with the'uppcr ends of said grooves; combinedwith an upper flame-spreading member hav-' ing flaring walls to'spreadthe flame and formed with a depression in the center of-its'under side to partially encompass 'the cone and'the depression in thelatter. r

2. A burner of the class described comprising a base having a centraldraft opening and an annulardrip channel, an integral ring rising fromthe base around said opening and forming the inner wall of said Ichannel, upwardly convergingarms formed integrally withsaid ring withsegmental openings between them, the upper sides of v conicalpart ofsaid basemember, and arms radiating integrally from said flaring wallwith their outer ends shaped to. fit within the surrounding wall of thebase member.

3. A burner of the class described comprising a base member providedwith fiar mg walls, an annular drip channel, a central oil receptacle,and radiating distributing channels between the oil receptacle and dripchannel, in combination with an upper and distributing channels betweenthe oil re ceptacle and drip channel in combination with an upper memberprovided with a depression to cover the oil receptacle, flaring walls tospread the flame, and radiating igember in inverted conical shapeprovided with a depression to.cover the oil receptacle,

arms having beveled outer ends fitting withinthe upper 'edges of theflaring walls of the, base member. 4 I In testimony whereof I havehereunto set my hand in presence of two subscribing witnesscs.
